In this paper, the analysis of sensor failure and corresponding fault tolerant control method for mechanical electric parking brake system was proposed, the estimation model for tilt sensor was built. The simulation model and PID controller was constructed based on Matlab. The hardware in the loop simulation platform was built with the AutoBox as a system control unit. The system control strategy was designed according to the function requirements of EPB system, and the corresponding control program was written in Matlab/simulink software. Finally, the feasibility of this fault-tolerant control system was verified by analyzing the bench test data.
